DYElNG-IVIACHINE.

SPECIFICATION' forming part of Letters Patent No. 519,323, dated May 8, 1894. Application filed January 23.1893. Serial No. 459,388. (No model.)

To @ZZ whom it may concern):

.l'e it known that I, GEORGE H. CEAVEN, a citizen of the United States, residing in the `city and countyof Philadelphia, in the State of Pennsylvania, have invented a certain new and useful Improvement in Dyeing-Machines, of which the following is a true and exact description, reference being had to the accompanying drawings, which form a part of this specification.

. My invention relates to machines for dyeing yarns in hanks or skeins and especially to machines where the yarn is carried for-` ward through the dye liquor in an open tank.

Asis well known, yarn has a better and more even tint when in addition to the compara` tively slow movement of the yarn through the d ye liquor, it is given, preferably when iirst immersed in the dye liquor a sudden push 'which tends to separate the yarns and permits the dye liquor to more effectually permeate them.` This sudden mot-ion of the yarn, called swilling? has heretofore been done b y hand and one of the objects of my invention is to provide automatic means for effecting this swilling, other objects are to provide improved; means for advancing and rey turning the yarn through the tank, for rotating the yarn carrying bars and for raising the Whole mass of `yarn out of the dye liquor, and my invention consists in means for giving the yarn a quick motion through the dye liquor during a part of its travel and invarious details of construction which tend to simplify and improve the action of the machine. The nature of my improvements Willbest be understood as described in connection with the drawings in which they are illustrated, and 1n which Figure l is a side elevation ofy a dyeing machine embodying my improvements. 2 Fig. 2 is a top ViewT of the dyeing machine shown in'Fig. l, representing some of the yarn carrying bars 1n position. Fig. 3 is a section on the lines orof Fig. l looking toward the right. Fig. 4 is a View of the left end of the dyeing machine shown in Fig. l showing the mode of applying power. Fig. 5 is a view similar to Fig. l showing some modifications. Figs. Gand 7 are views of myiniproved means for turning the yarn carrying bars, and Fig. 8 y is a detail of the'forward pins on the racks F.

A represents a dye tank or vat of ordinary construction in which is contained the dye liquor, and K represents yarn bars on which are hung the `hanks of yarn 7c Which are to be dyed. On one end of this tank running in bearings a is a shaft a. which has at each end a sprocket Wheel b. Power is applied to this shaft at B in any convenient way as by a lower shaft with a pulley et, and all parts of the machine are operated by chains b on the` sprockets b.

The connections on both sides of the inachine are alike and a description of one side clearly describes both.

y Pivoted on the side of the tank are sprocket wheels d and c to which motion is imparted by the chain b'. The sprocket wheel d has formed with it a gear wheel d', shown in Fig. 3, which meshes with a gear wheel c pivoted on the side of the tank at p. Thegear wheel c is fastened on a sleeve r and the sleeve r carries on its outer end the arms E. The arms E have at their outer end sockets N formed of tWo parts n and n Fig. 6 as will be hereinafter p more fully described. The sprocket Wheel c carries arms C. The sprocket wheels b and d are of the same size and so move with the same speed and have set in corresponding po- 8o sitioii, pins; a pin f, in the sprocket b anda pin f', in the sprocket el; carried ,on these pins is a notched rack F and constitutes a carrier for theyarn carrying bars and which has a rotary motion of as great an amplitude as the distance of the pinsf,f, from'the center of I the Wheels which carry them, and which rack is designed to carry forward the yarn bars as hereinafter explained..

F', represents a second rack, also notched to fit the yarn bars which is stationary on the edge of the tankbut maybe connectedto an operating part of the machine and lifted to remove the yarn from the dye tank as will be hereinafter explained. The gears `of gear rack by the oscillating bars F at each revoluaxis rotates the sleeve r which carries the' gear wheel e and bars E. To this pivot is fastened a stationary bevel wheel s which l meshes with the bevel wheels', this by means lzo of a rod 'm is connected to a bevel wheelt which meshes with a bevel wheel 25. The bevel wheel t has a shaft t which extends through the arm E and carries the pocket n fastened thereon so that this pocket will turn with the bevel wheel 1f', but on the inside of the arm E. This pocket is designed to pickup the yarn rods as will be hereinafter more fully described, and is shaped to t the yarn bars. Outside of the pocket n and loosely pivoted on its Shaft t so that it can turn and always preserve its upright posit-ion is a second pocket a, which will prevent the yarn bar K from falling out 0f the inner pocket when this inner pocket is turned as seen in Fig. 7. The two form the socket N which picks up a yarn bar and carries it to the rear of the tank and at the same time turns it over.

At the rear of the tank A are two standards w carrying pulleys W for raising the racks F and the yarn bars when desired. A small idle wheel D is provided to more effectually guide the sprocket chain b and guides H for the yarn bars may be used as seen in Fig. l.

The operation is as follows: Hanks of yarn 7c are hung on rods K and are partially immersed in the dye liquor as is shown in Fig. 3; many bars K can be used at once each fitting into a different notch o, o', in the inner racks F. Power is now applied at B and the sprocket wheels ZJ and d and the bars E and the sprocket wheel c which carries the arms O are all caused to turn. As the wheels b and d revolve the racks F one on each side of the vat have a corresponding rotary motion each point of the bar F describing a circle of as great radius as the distance that the pinsjf, of the wheels b and cl are from the center of those wheels. This motion of the bar F is such that it picks up a yarn carrying stick out of one notch o of the rack F and deposits it in the next notch o', so that with each revolution of the wheels Z) and d, the whole body of yarn is carried forward a distance equal to the space between the notches. When a yarn carrying bar reaches vthe last notch of the frame F it is in line with the sockets N on the revolving bar E, since these-yarn bars as will be seen from Fig. 3 project some distance from the side of the dye Vat and are guided by guides H fastened on the side of the vat. That yarn carrying bar therefore which is in line with the socket N is picked up by the rod E as it revolves and carried to the rear of the vat, and while being so carried is turned over by the gear on the arm E and thus a new portion of the yarn is brought into the dye liquor. Vhen the rod is deposited at the rear of the vat by the rods'E it is struck by an arm O fastened on the gear wheel c and quickly pushed along the edge c of the tank linto the first notch ot' the rack F whereit commences its forward 1 journey again. The forward movement of the yarn bars is thus accomplished by two separate means, each of which gives the yarn barsa different speed, one consisting of the rack bars F which slowly move the yarn through the dye7 and the other means being the arm C which gives the yarn a sudden forward movement through the dye as soon as it is returned tothe rear of the tank by the revolving arms E. This quick movement of yarn in the dye stuff which has heretofore been done by hand, is by my'improt-ement accomplished automatically by the arms C which give the yarn bars a quick forward motion along the edge of the tank and so carry the yarn suddenly through the dye which operates to separate the yarns and gives them more evenness of tint. When it is desired to remove the yarn from the vat the inner rack bars F are bodily lifted from their position on the edge of thetank. These racks F are connected at the rear by a cross bar G and have at the front two guide arms g which serve to prevent the springing of the disconnected front ends and make a rigid frame of the racks F. At the forward end of these racks are pinsP formed in two parts as seen in Fig. 8 and so arranged that the pins may slide together .to be out of the way during the operation of the machine and slid out to come in line with the sockets N of the bars E when the racks F are to be raised; and at the rear of racks F are pins P. When it is desired to raise the racks F one end of a chain R is fastened to either ot' the rear pins P', the chain is passed over pulleys W arranged on the standards w at the rear of the vat and the other end of the chain is fastened to the left end of the bar E as seen in Fig. l, the other end of the bar E raising the forward end of the bar F by means of the sockets N which are in line with the pins P when these are slid out. If now powerbe applied, or if the bar E be turned by hand the rack bars F will be raised and all the yarn will be removed outof the dyeliquor as shown in dotted lines in Fig. l.

Instead of the means described for turning the inner pockets n the device shown in Fig. 5 can be used.

Fastened to the pivotp is a plateland pivoted in this plate eccentrically to the main bar E is a rod L which is toothed at both ends and meshes with a toothed wheel L which carries the shaft t of the pocket n; as the bar E turns the rod L will move relatively t0 it and turn the gear wheels L and the sockets of the yarn rods.

IOO

IIO

Various other devicessuch as an eccentric or any similar `device which would` readily suggest themselves to a skilled mechanic may be used to turn the pockets n', and I do not` wish to be confined tothe `means shown. By increasing or diminishing the relative size of the bevel wheels or the distance of the rod L from the center of the bar E the distance which the pockets n are turned can be regulated, and this regulates the amount of yarn `which is newly put into the dye liquor each tlmve the yarn is carriedlfrom the rear to the frontof the tank. Also instead ofthe sprocket vention into effect, but it is evident that many other means may beused without departing from the spirit of my invention. The inner rack F may be dispensed with altogether if desired and yarn bars be moved forward on the edges of the tank. The racks F, F', may be dispensed with and any suitable means such as a reciprocating slide or chains as shown in my Patent No. 417,908, granted December 24, 1889, or any other similar means may be used to give the yarn bars a steady or lntermittent forward motion. The raising of the yarn bars and the yarn may be done as has been shown entirelyby the action of the machine which is a very great advantage where large weights of yarn have to be raised.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-
